Most states have laws requiring that you pass under bridges at a slow speed. You should always reduce your speed and proceed with caution near any bridge or man-made structure that decreases visibility and passage.
- Many bridges are high enough to allow normal boat passage. However, some bridges provide only low clearance during normal conditions or periods of high water.
- Many drawbridges open and close when a boat arrives. To request passage, contact the bridge operator using sound signals or a VHF marine radio.
- Be aware that debris can collect around pilings of bridges and create dangerous obstructions.
